Description

Technical Field

[0001] The invention relates to the technical field of planting hole digging, and in particular to a planting hole digging device for plant planting. Background Art

[0002] The planting hole, also known as the planting hole or tree hole, is a hole dug around the designated planting point before planting the seedlings. The size of the planting hole should be determined according to the size of the seedlings.

[0003] When digging a planting hole, it is necessary to pay attention to the vertical surface of the planting hole being perpendicular to the bottom surface, and the upper and lower sizes being consistent. It should not form a pot-bottom shape that is larger at the top and smaller at the bottom. Otherwise, the root system of the planted trees will be damaged when the soil is filled in layers and stepped on.

[0004] In order to increase the speed of digging planting holes, most people nowadays use drilling rigs to drill planting holes. The planting holes drilled by such drilling rigs are mostly cylindrical with the same size at the top and bottom. However, there are certain limitations on the drilling rigs used for digging planting holes. Due to the limitations of the drill column of the drilling rig, only cylindrical planting holes can be dug. In some arid areas, in order to reduce water evaporation, the planting holes need to be dug into trapezoidal holes that are small on the top and large on the bottom. In addition, since the loose soil will accumulate at the edge of the planting hole after being brought out by the rotary blade, the planters need to step on the accumulated loose soil to plant, which is very inconvenient.

[0036] The linkage shielding mechanism includes a linkage extrusion rod 7, a guide cross frame 8 and a shielding member 9. The guide cross frame 8 is arranged at the bottom end of the mounting base 1. The shielding member 9 is horizontally slidably installed on the guide cross frame 8, and the shielding member 9 is opposite to the excavation rotary blade 512. One end of the linkage extrusion rod 7 is rotationally connected to the shielding member 9, and the other end is rotationally connected to the lifting control component 3, so that when the lifting control component 3 controls the driving motor 4 and the adjustable hole digging rotary frame 5 to move downward, it can synchronously drive the shielding member 9 to move forward horizontally and close to one side of the excavation rotary blade 512, so as to form a shield when the excavation rotary blade 512 rotates to dig the planting hole, thereby forming a space without loose soil on one side of the planting hole, which is convenient for subsequent staff to carry out planting work on this side.

[0037] The double-layer sliding shovel blade 521 includes an upper and lower shovel blade. The upper shovel blade is fixedly arranged at the bottom end of the excavating rotary blade 512 in the horizontal direction, and a guide groove is provided on the upper shovel blade. The lower shovel blade is slidably installed below the upper shovel blade along the length direction of the upper shovel blade, and the lower shovel blade fits tightly with the upper shovel blade. The regulating end of the regulating component 6 passes through the guide groove and is connected to the lower shovel blade, so that the lower shovel blade can be controlled by the regulating component 6 to slide outward under the upper shovel blade.

[0038] Among them, the upper shovel blade and the lower shovel blade both include a horizontal plate body and an inclined shovel blade part, the inclined shovel blade part is away from the excavation rotary blade 512, and the lower shovel blade is also provided with a guide plate that fits the bottom surface of the excavation rotary blade 512, so that the double-layer sliding shovel blade 521 can shovel the soil through the inclined shovel blade part and guide it to enter the excavation rotary blade 512 and rotate it out.

[0039] The regulating assembly 6 includes an extrusion frame 61, a connecting sliding shaft 62 and a regulating push rod 63. The output end of the regulating push rod 63 is vertically downward and arranged on one side of the end of the hollow rotating shaft 511. The connecting sliding shaft 62 is slidably arranged inside the hollow rotating shaft 511, and the end of the connecting sliding shaft 62 is connected to the output end of the regulating push rod 63. One end of the extrusion frame 61 passes through the guide groove and is rotatably connected to the lower shovel blade, and the other end is rotatably connected to the bottom end of the connecting sliding shaft 62. When the double-layer sliding shovel blade 521 is connected to the excavating rotary blade 5 12 After being screwed into the ground, the regulating push rod 63 can be started to drive the connecting sliding shaft 62 to move downward inside the hollow rotating shaft 511, and the squeezing frame 61 and the lower shovel blade are squeezed by the bottom end of the connecting sliding shaft 62, so that the lower shovel blade slides outward along the length direction of the upper shovel blade, thereby increasing the shoveling radius of the double-layer sliding shovel blade 521. After the double-layer sliding shovel blade 521 and the excavating rotary blade 512 are screwed into the ground, the shoveling radius of the double-layer sliding shovel blade 521 is increased, which can make the screwed planting hole appear narrow at the top and wide at the bottom.

[0040] The return spring 522 is arranged at the bottom of the inner side of the hollow rotating shaft 511, and the end of the return spring 522 is against the bottom of the connecting sliding shaft 62, so that the connecting sliding shaft 62 squeezes the return spring 522 for compression when moving downward. When the planting hole is completed, the regulating push rod 63 is closed. At this time, under the reverse elastic force of the return spring 522, the connecting sliding shaft 62 is driven to reset, thereby facilitating the next time the regulating push rod 63 drives the connecting sliding shaft 62 to move downward.

[0041] The lifting control component 3 includes a lifting slide 31, a driving cylinder 32 and a guide reset component 33. The guide reset component 33 is vertically arranged on the vertical frame of the mounting base 1. The lifting slide 31 is slidably installed on the guide reset component 33. The drive motor 4 is arranged on one side of the lifting slide 31, and the drive motor 4 is located on the side of the mounting base 1 away from the side support roller 2. The drive cylinder 32 is vertically arranged on the side of the mounting base 1 away from the drive motor 4, and the output end of the drive cylinder 32 acts on the side of the lifting slide 31 away from the drive motor 4, so that the drive cylinder 32 can drive the lifting slide 31 to move up and down on the guide reset component 33, thereby driving the drive motor 4 and the adjustable hole digging rotary frame 5 on the lifting slide 31 to move downward, and the adjustable hole digging rotary frame 5 is used to rotate and dig planting holes on the ground.

[0042] The linkage extrusion rod 7 includes a base rod 71, a sliding rod 72 and an extension spring 73. One end of the base rod 71 is rotatably connected to the bottom end of the lifting slide 31, and the other end is provided with a slot. One end of the sliding rod 72 is rotatably connected to the shielding member 9, and the other end is movably inserted into the slot of the base rod 71. The extension spring 73 is arranged between the base rod 71 and the end of the sliding rod 72, so that the entire linkage extrusion rod 7 can be extended and restored.

[0043] A horizontal guide slot is provided on the guide cross frame 8, and the shielding member 9 includes a sliding frame 91 and a shielding plate 92. The sliding frame 91 is slidably installed in the guide slot of the guide cross frame 8, the shielding plate 92 is arranged at the end of the sliding frame 91, and the sliding rod 72 is rotatably connected to the shielding plate 92.

[0044] Among them, the baffle plate 92 is facing the excavation blade 512. When the lifting slide 31 moves downward, the sliding frame 91, under the guidance of the guide cross frame 8, can squeeze the baffle plate 92 close to the excavation blade 512 through the linkage squeezing rod 7. When the excavation blade 512 collides with the excavation blade 512, the lifting slide 31 continues to move downward to compress the linkage squeezing rod 7.

[0045] The guiding cross frame 8 includes two parallel cross frames, and both cross frames are provided with guiding long grooves. The two ends of the frame body on one side of the sliding frame 91 are respectively slidably set in the guiding long grooves of the two cross frames, and the frame body on the other side is fixedly connected to the shielding plate 92. The guiding long grooves of the two cross frames guide the two ends of the sliding frame 91, so that when the sliding frame 91 and the shielding plate 92 move forward, the forward movement direction can be kept facing the excavating rotary blade 512.

[0046] Working principle: first push the entire device to the position where the planting hole needs to be dug, and lay the mounting base 1 flat. At this time, the hollow rotating shaft 511 and the digging rotary blade 512 are perpendicular to the ground, and the driving motor 4 is started to drive the hollow rotating shaft 511 and the digging rotary blade 512 to rotate, and then the driving cylinder 32 is started to drive the lifting slide 31 to move downward along the vertical frame of the mounting base 1 under the guidance of the guide reset component 33, thereby driving the driving motor 4 and the adjustable hole digging rotary frame 5 on the lifting slide 31 to move downward. When the hollow rotating shaft 511 and the digging rotary blade 512 move downward in a rotating state, they will rotate and dig directly against the ground. When the digging rotary blade 512 is screwed into the ground, the double-layer sliding shovel blade 521 is also screwed into the ground at the bottom end of the digging rotary blade 512. At this time, the regulating push rod 63 is started to drive the connecting sliding shaft 62 to move downward on the inner side of the hollow rotating shaft 511, and squeeze the lower shovel of the squeezing frame 61 and the double-layer sliding shovel blade 521 through the bottom end of the connecting sliding shaft 62. The blade makes the lower blade of the double-layer sliding shovel blade 521 slide outward along the length direction of the upper blade, thereby increasing the shoveling radius of the double-layer sliding shovel blade 521. In the process of the double-layer sliding shovel blade 521 and the excavating rotor 512 rotating downward, the shoveling radius of the double-layer sliding shovel blade 521 is increased, which can make the rotated planting hole appear narrow at the top and wide at the bottom. In addition, when the lifting slide 31 moves downward, the lifting slide 31 will squeeze the baffle plate 92 through the linkage squeezing rod 7. At this time, the sliding frame 91 and the baffle plate 92 will move in the direction of the excavating rotor 512 under the guidance of the guide cross frame 8. When the baffle plate 92 is attached to the outside of the excavating rotor 512, the lifting slide 31 continues to descend to squeeze the linkage squeezing rod 7 to shorten it, so that the baffle plate 92 is tightly attached to one side of the excavating rotor 512, thereby forming a shielding on one side of the excavating rotor 512. At this time, the excavating rotor 512 will not be able to accumulate on this side when bringing out loose soil, thereby leaving space for the planting personnel to work.
